1- Objetivos:
Verificar en la práctica los valores teóricos de polarización y las potencias disipadas para
un amplificador mono etapa clase A.
2- Lista de Materiales (este T.P. es INDIVIDUAL)
- se entregara una plaqueta por alumno
3- Realización
En el laboratorio se le hará entrega a cada alumno de una plaqueta armada con el
siguiente circuito.
R1

RC
Q1-collector
Q1
BC547C
R2
RE
GND
conteniendo los siguientes materiales
R1=410K
R2=164K
RC=2K2
RE=520 ohm
Q1; BC547C
Vcc=10v
- Hallar los valores teóricos de polarizacion ICQ y VCEQ. Para ello, tener en cuenta el
rango de variación de los valores de hFE (min y max) dados en las hojas de datos de los
transistores correspondientes. Todos los cálculos se insertan en la hoja que sigue
